Fig. 1From: Evaluation of whole-genome DNA methylation sequencing library preparation protocolsRaw read statistics for each protocol. Each plot shows the percentage of bases with different levels of base quality, namely low base quality (< 20) for AÂ read 1 and BÂ read 2, medium base quality (\(20 \le\) quality \(\le 30\)) for CÂ read 1 and DÂ read 2, and high base quality (> 30) for EÂ read 1 and FÂ read 2Back to article page
